Re: Nvidia 6200 and ATI RS480/482 chipset incompatibilities
The people who reported issues were using either a 6200TC or a 7300GS. Boththe 6200TC and the 7300GS are equipped with TurboCache support. More advanced Nvidia boards (6200 non-TC, 6600, 6800, 7600, ..) don't support TurboCache it is only used on various lowend boards (I think on 7100/7200 cards aswell). As I mentioned I'm using a rd480 with a 6600gt and don't have issues, the same for someone who moved from a 7300GS to a 6600.
I think the issues only appear for cards using TurboCache. I don't know this for sure but based on my result combined with the results of a user who moved to a 6600, it seems to be related.
